This is required to allow the sscape driver
to autodetect installed codec.
Also, do not create a timer if detected codec
has no hardware timer (e.g. AD1848).

Use the wss_dout function which does not mess
shadowed register values during chip probing.
Otherwise, user ends up with stupid mixer settings
after driver loading.

Make snd_ad1848_probe() easier to follow. With an exception for only
trying once as soon as the codec is out of init (which should be all
that's needed) the detection logic should be unchanged.

After the transition from cs4321_lib to wss_lib, azt2320 probe visits
snd_ad1848_probe during detection. It expects register 0 (LEFT_INPUT)
to be able to retain the value 0xaa during detection but AZT2320 does
not support MIC gain meaning it reads back as 0x8a instead.

Remove initializations of spinlock and mutexes which
are done earlier in snd_wss_new(). The snd_wss_new()
is called from snd_wss_create().

Use the wss detection code and kill the ad1848 library.
The library is fully assimilated into the new wss library.
This required reworking of the AD1848 family code
so the code is changed to correctly detect chips from
the AD1848 and CS4231 families.
I have tested it on following cards:
Gallant SC-6600 (codec: AD1848, driver: snd-sc6600)
SoundScape VIVO/90 (codec: AD1845, driver: snd-sscape)
SG Waverider (codec: CS4231A, driver: Rene Herman's snd-galaxy)
Opti930 (codec: built-in - CS4231 compatible, driver: snd-opti93x)
Opti931 (codec: built-in - CS4231 compatible, driver: snd-opti93x)
Gallant SC-70P (chip/codec: CS4237B, driver: snd-cs4236)
Audio Plus 3D (chip/codec: CMI8330A, driver: snd-cmi8330)
Dell Latitude CP (chip/codec: cs4236, driver snd-cs4232)
Sound playback and recording works on all these cards.

Use the wss pcm code and kill the ad1848 pcm code.
The AD1848 chip is much slower than CS4231 chips
so the waiting loop was increased 100x (10x is not
enough).
